Raised and educated in the Midwest I first came to NM for residency training and haven’t wanted to leave the land of Enchantment. I enjoy outdoor activities with family and friends especially cycling, climbing, backpacking, and exploring.
I am very interested in advancing research activities in the acute care setting. I help run a course on research in the Emergency Department, support multiple levels of learners complete research, and have my own area of research focus.

My research interests focus on understanding the pathogenesis of infectious diseases in the acute care setting. My primary interest is in the pathogenesis of Staphylococcus aureus, specifically examining the host defects that lead to incomplete control of bacterial communication in patients presenting to the Emergency Department. We are translating our molecular understandings of bacterial virulence control into the clinical setting. We examine patients and infections along a full clinical spectrum from preventing infection in those at risk after trauma, treating simple skin and soft tissue infections, and finally to those who present with severe sepsis and septic shock.

My research into the changes in immunity that occur during times of physiologic stress have also contributed to investigations into the physiologic changes that occur while engaged in strenuous activity. This has led to a collaboration with the National Park Service to examine the changes that occur in hikers crossing the Grand Canyon.
